NOTES

1. If sensor is connected in reverse (copper wire to AG terminal and silver wire to CU terminal), the voltage across the two

terminals will measure approximately .7vDC. Controller must be "On".

2. If sensor connected with reverse polarity, the display should read 00.
3. Cannot check sensor by disconnecting leads and measuring ohms, but ohmmeter can be used to check for bad sensor

(infinity would = open and continuity = shorted).

4. If sensor is open or lead broken/disconnected, the display will show the setpoint.
5. If sensor appears to be OK, try reconnecting to either R1 or R2 input terminals. If controller now works OK, something

wrong with "Loc" input circuit. OK to leave this way.

6. If more than one sensor is connected and one fails, the controller will operate OK from the functional sensor.
7. If only one sensor and it fails or is disconnected, 1st stage cooling will default "On" if it was calling for cooling when

sensor went out. If additional stages were on at the time, they will turn off.
